City of Memphis / Shelby County
City of Memphis and Shelby County have a unique relationship. They have a joint partnership in administering Steam Engineer's and Refrigeration Engineer's licensing for operators. Also, the county seat is in the City of Memphis.
First, the City of Memphis has an active statute on boiler attendents as follows:
Sec. 14-12-48. Boiler attendants.permanent link to this piece of content
Every owner or user of any boiler or steam generating apparatus, when such equipment is in use, shall have a licensed engineer of the grade required on duty at all times as provided for in section 46-12 of the city's 1967 Code of Ordinances.
(Code 1967, § 45-68; Code 1985, § 42-72)
This is where the County of Shelby comes in, for the County administers a Mechanical Contractor license program, which is a joint commission of the joint Memphis and Shelby County Mechanical / Gas Code Board consisting of:
- Four members appointed by the mayor of Memphis and confirmed by the Memphis City Council
Four members appointed by the Shelby County mayor and confirmed by the Shelby County Commission
Now, all licenses expire December 31 each year and must be renewed in December.
